READMAKE is a DOS utility for creating a DOS EXE file that, when executed, displays a text document in a full-screen viewer. It was developed by Bruce Guthrie and Wayne Software.

READMAKE is related to READ (a.k.a. READ.EXE), a text file viewer by the same developer.

[edit] Identification

The executable part of a generated file is compressed with EXEPACK.

The EXE code segment (refer to MS-DOS EXE#Special file positions) at offset 512 starts with ASCII "blREADINCL". While not a deliberate signature (it's some sort of linker artifact?), it could be a fairly effective way to identify the files.

The overlay always starts with the same 62 bytes, the first four being 3e 00 00 00 (presumably a segment size field). However, some other EXE files from the same developer also have this trait.

[edit] Software

READMAKE was usually packaged with other software by the same author. The individual programs have revision dates that serve as their version numbers. Each package as a whole has an apparent 3-digit version number, probably loosely derived from the release date.
